-To` ull whom it may concern:

' Be it knownl that we, ALBRT W. Co'r'rnnLL and MILTON MOORE, citizens of the United States, resldmg at Douglas,in the county of of Arizona, have -inlng is a specification.

Our invention is in the nature of a new 10l explosionengine of the rotary type designed to secure from the successive explosions of thecharge a continuous rotary motion in one direction.

'It belongs to that class thev shaft bearing a rigid hub porcasing revolves thereon;

Figure 1 is a central longitudinal section. Fig. 2 is a transverse section in two planes,

'- Fig. 3 are details,-in end and side views, of one of the movable abutments, and Fig. 4 is In the drawing the numeral 1 represents a hollow shaft provided in the middle with a partition p separating the hollow `space in said shaft lnto two parts, the one `on the sideof Fig'. 1 being the intake and the one on the'left hand side being the exhaust.

2 is a stationary hub rigidly attached to lthe-shaft 1, and 3 is the rotating cylinder or caslng having opposite ends Aor'heads 15 turnlng together on said hollow shaft. f ,Rlgldly attached to the interior of the r'evolving casing are2 three (more or less) in-f wardly projecting lugs, 4, see Fig. 2, extendwhich abutments are adapted to turnl into recesses in theperiphery of the hub in passing by the'piston heads 4 and after passing said piston heads the abutments swing outwardly V to the inner periphery of the revolving cylinder to form explosion chambers. 5a are cam lugs secured to the inner side 'ofthe abutments' 5 at some distance from 5 their-axes and arranged to'actupon and to open slide valves 6. Whenthe abutment is closed as at the bottom ofxFig. the said lugs ofl rotary engines 17 is the mixing'i'chamber, 'sage tothe gasolene tank 20, and 19 the gaso- 'lene pipe controlled by the valve 19aL ltending into the mixing chamber 17 to a ing to and having-a packed bearingagainsty valve l and the carburetor end of the hollow shaft.

.5a press the slide valve toward the axis of the abutment to uncover port 10. 5b'are similar lugs located near the centers of said abutments and designed to act upon and to close the slide valves 6' by pressing -against `the opposite side of the valve 6 and forcing it across the port 10 as at the to'p of Fig. 2.

These valves 6' thus 'control the ports 10 and' separate the explosion chambers of the cylinwithin the hollow shaft.

-der from-the carburetor which is contained 7 are sparkingv terminals which are arranged in-suitable insulating plugs located within the recesses' of the central hubl and close, said,

mitted to the explosion chambers 11.

12 are radial exhaust' ports through the solid hub. l,

12al are exhaust port-s nthrongh a disl; ring 24. 4. t

13 is the exhaust end of the shaft, 14 an exhaust chamber surrounding the same and arranged between lthe end plate 25 and' ring 24 on one side'and the cylinder head 15,1011 the other.

16 is the inlet air pipe.

and eX- spraying device 23.

21is an inwardly opening spring seated valve arranged in the air pipe' 16 located between the air passage 18 and the gasolene pipe 19, and 22 is a similar spring seated arranged between the mixing chamber 24 is a ring forming one end of the ex.

18 an air pasplosion chamber and lylng in the Asame plane `with av plate 254 on the end of the stationary central hub 2. `2G is a central rotary balanced throttle valve controlling the ports '10 and having a longitudinal stem arranged in the yhol-low ,shaft and operated .byV arod 27.

28, Figs. 2 and 4 is asmallspringv fas tened to each valve Gand insulated from the i same and arranged to close-fthe; circuit CTI air current in the niixing ehamber 17, is

-tho valve G into the explosion chambers 1l,

through the sparking terminals 7, by bric gl ing across a gap a; in the sparkterminal cir cuit wheneve a valve (l is ioreed across port, l() to olose it.

29 is a safety valve arranged in the intake end olf the hollow shaft. i

The operation of our rotary explosive engine is as follows; Air, under a suitable de gree of compression taken trom a eompressor or receiver, enters the pipe lo, passing through the valve 2]. and the small pipe 1S into'the gasolene tank 90 whereby the air y pressure is given to the gasolene. The spring on the valve 2l is made stronger than the spring on valve which makes the pressure on the gasolene greater than in the mixing chamber 17, and which is regulated by the valve lila. The gasolene coming in contacty I witl the spraying device 223 and meeting the l thoroughly broken up so as to be in a perfect'y gaseous state, as it: passes through the valve 22 into the carburetor fl. Then the gas passes through the radial inlet ports 10, past att'he same time by its pressure raising the swinging abutments fi which aetV as cylinder heads. At the .same time that any abutment is fully opened its eams or lugs o elose its valve t3 over itsl port l() and the eireuit elosing spring 2S, tas-tened to said valve butzinsulat'ed from it, eomes in contact with the two terminals o'lE the wire oi" the spark plug, thus closing the circuit' in the same and liring the charge of gas in the explosion chamber. This explosion causes pressure to be exerted on the revolving pistons 4A. thereby turning the outer cylinder or casing. llhen any piston 4- reaohes the next abutment 5 it eauss said abutment to close down into its in the hub. The burned gases ou the exhaust side ot the abutments escape through the exhaust' ports 12, l2 into the vhollow end 13 ot the shaft and thence trom the engine. The ports 12 are open behind the abutments when the abutments are open and are closed when theI abutments are closed. lVhen an abutment closes down, the cams or lugs 5 acting upon the valve t3. cause it to be reopened in the next .fhamber, where the same action of explosion is repeated.

ln our rotary explosion engine, it will be seen that we have three explosion chambers and four leed valves whieh are capable of eausing twelve explosions at every revolution and the explosion ehamliiers being long admit of the exploded gases expanding .to atmospheric pressure betore leavil'ig the engine` thus giving more power t'rom a given amount olt'uel and reducing the noise ot' exhaust to a minimum and at the same time acting as a Cooling agent to the engine. The air being compressed and cooled before being mixed with the gasolene, lessons the danger ot' ln'emature explosion and aids in keeping the engine cool, and our explosion en`- gine 'eau be stopped and started and the speed regulated with the throttle. An importantI l'eature ot" our invention also resides -in the tact that the inlet and exhaust ports in the hub open into the peripheral recess into which the hinged abutments shuty down and the spark terminals in like manner are also located in these reeesses, so that who]l hinged abutment is elosed over the same, the outer side ot the hinged abutment t'urnishes a smooth eireular surtaee that completes the periphery ot the hub tor the revolving pistons to slide on, and houses and protects the outer edges ot the ports and the spark terminals.
